Consider the motion of a projectile P of mass mP = 18.5 kg, which is shot with an initial speed υP = 1675 m/s as shown in the figure. Ignore aerodynamic drag forces.

Choose point O as moment center. Then verify the validity of the angular impulse-momentum principle as given in Eq. (5.65) by showing that the time derivative of the angular momentum does, in fact, equal the moment.
